Yes Don... that  makes sense   but  were there also  some instances of  pre 
war 15  wood tables!?  I can't   put  my finger on the  photos  but I 
thought I had  some  prewar 15s on  wood.  was it an option in some instances?

WOOD  TABLES WERE USED ON THE M26 FOR PAPER HANDLING.
WOOD TABLES FOR THE 15, 19,  AND 20 WERE USED DURING WWII DUE TO SHEET 
METAL  SHORTAGES.
